EXTENSION WORK FOR PORT OF LOBITO—MINERAL TERMINAL
1. Brief Introduction of mountain excavation The project lies in the back of 310 mineral quay. The total quantity of mountain excavation is 2,650,000.00m3. In fact, we will transport around 3,445,000.00m3。 Since the quantity of mountain excavation is rather large, enough trucks and excavators are needed to meet the productivity 10000m3 per day. The excavated rock should be clarified to stock. During exploiting the rock material with the explosive method, measures should be taken to make the exploited rock material meet above requirements. The surplus rock material will be transported to the construction site to backfill. Besides, about 1,000,000.00m3 rock material will be implement waste disposal plan. 2. Mountain excavation technical plan First of all, the surface of the mountain should be unsoiled and a 1500m long construction gangway will be built. Different grain diameters of rock will be used in the project. It is designed to
